Engineered with all-around laser welding and a built-in resistor, these plugs ensure reliable, interference-free performance tailored for vehicle-specific fit and durability. ## Description The two needle-thin electrodes in DENSO’s patented Iridium TT design enable sparks to grow 360 degrees in all three dimensions, improving ignition performance and combustion output, increasing spark plug lifespan and reducing emissions. The lifetime of these plugs meet any OE engine maintenance requirement. Performance is higher due to the Twin tip technology and the Denso patented 0.4mm centre electrode Review: 2011 Corolla - Great as expected. Review: Good spark - So far they've been a great replacement for my 2016 Nissan versa Note. Replaced the original NGK platinums with these at about 94,000, mi.. I dare say My engine is running a bit smoother and think I'm getting a better gas mileage. Aside from ngks these denso brand parts seem to be holding up really well. I have also used a fuel pump from them and a few other things on a different car. All four of these were gapped correctly. Fitment was great!. And they seem to have a strong spark. Now changing out spark plugs on your Nissan versa is a real pain in the bum.. there are some really good videos however. very much worth it, especially once you get to the 100,000 mile mark. ## Features - IXEH20TT | Twin Tip Plug | Tightneing Torque (Nm): 17 | 1 - Earthed Electrode | Diameter (mm): 12 | Thread Length (mm): 26.5 - The Finest Twin Tip plug with improved acceletation, fuel economy and longevity compared to single tip plugs. The quenching effect has been decreased by forming the electrode into a double needle shape. As a result, the flame kernel rapidly develops and the engine’s power is drawn out to its maximum potential. DENSO IRIDIUM TT spark plugs have a φ0.4 mm iridium alloy center electrode and a 0.7 mm needle-type platinum alloy ground electrode. - The iridium tip is mounted with an “All-around Laser Welding” method that insures high reliability even under the most severe driving conditions. - Using DENSO’s exclusive iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability. - All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XSQ2C5M | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #108,339 in Automotive ( See Top 100 in Automotive ) #720 in Automotive Replacement Spark Plugs | | Brand Name | Denso | | Compatible with Vehicle Type | Car, Van | | Core Material | Platinum | | Customer Reviews | 4.5 4.5 out of 5 stars (60) | | Included Components | Iridium TT Spark Plug x4 | | Item Type Name | Spark Plug | | Manufacturer | DENSO Corporation | | Manufacturer Part Number | IXEH20TT | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Model Number | IXEH20TT | | OEM Equivalent Part Number | 1611548180, 1N1918110, 224011HC1B, 224018760R, 9091901253 | | Thread Size | 14mm | | Top Material Type | Ceramic | | UPC | 042511471146 | | Unit Count | 4.0 Count | ## Product Details - **Brand:** Denso - **Core Material:** Platinum - **Thread Size:** 14mm - **Top Material Type:** Ceramic - **Vehicle Service Type:** Car, Van ## Images ![Iridium TT Spark Plug - 4711 (IXEH20TT) (4 Pack) - Image 1](https://m.media-amazon.com/images/I/71RjREPZYrL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 2011 Corolla *by A***I on March 8, 2026* Great as expected. ### ⭐⭐⭐⭐⭐ Good spark *by M***D on March 14, 2025* So far they've been a great replacement for my 2016 Nissan versa Note.
